Technical 30's KEM Dist. Cap I.D. Requested

Anybody have a KEM catalog from the '30's to the 50's that could identify a NOS distributor cap I have? The cap is in a KEM box with a p/n of 1496DB and somebody wrote '31-'32 Auburn" on it. I'd just like to confirm that that's correct.
Thanks,

Gotta picture of it? Also look inside the cap, lots of them had a part number inside the cap.

 

Just dawned on me that the cap is for a 6-cyl. cap and Auburn didn't have any 6-cyl. engines in 1931, '32 or '33. I guess I need a KEM catalog to locate the number. Picture of it is below - cap is 2-5/8" diameter at the base.
Thanks,
-Bob
